2006 Connect T220L SWB 1.8 Diesel. No engine management light on when key turned in ignition on starting. It doesn't come on when there is a fault either, e.g. cooland sensor failure.
I have run the cluster self test and the EML does illuninate, so the LED is good. All other dials/guages/LEDS work fine.

 

It has been suggested on another forum, that the problem is probably a processor communication to the CEL fault/malfunction.


I cannot afford to pay £150+ to take it to a Ford garage to be put on a diagnostic tool.


How would I go about getting this investigated?

 

Sometimes you simply have to spend money if you need to get something done


on the other hand, if you don’t have any actual problems other than the light itself, just leave it as is
